Causes of Fascial restriction, When the fascia is injured whether through direct trauma, repetitive strain, or even injury to a related structure like a spinal disc it undergoes a series of specific physiological changes that fundamentally alter its structure and function.
Scientific evidence suggests that "muscle injury" is often a misnomer, as the vast majority of such traumas roughly 90% actually involves the myotendinous junction and the interface where the muscle meets the fascia.
When a muscle or related structure is injured, the body initiates a repair response that can lead to fibrosis, which is an overproduction of collagen and the deposition of a dense collagen matrix.
This excessive collagen synthesis results in tissue adherence, effectively "tethering" layers of fascia to each other or to the underlying muscle, which limits their ability to glide freely.
Furthermore, injuries trigger the release of pro-inflammatory cytokines that can "spill over" from the site of muscle trauma into the surrounding fascial network. This creates a vicious cycle where persistent inflammation leads to ongoing tissue damage and a change.
Global Migration: An injury in one area, such as the right rib cage, creates a "snag" in the suit that can migrate through the network, causing pain or restricted range of motion in a completely different area, like the opposite shoulder.
